' As shown on the drawings:

The slide fastener attaching device of this invention is adapted for the convenient and rapid assemblage of the parts of a coin purse, toilet cases and containers and similar articles which are closed by slide fastener type closure mechanisms which extend around a major portion of the periphery of a coin purse or the like when closed and which extend entirely around the peripheral edges of the covers of the purse when open. A similar coin purse is shown in my copending application Serial No. 203,989, filed April 25,- 1938.

The improved zipper attaching device of this invention will be described in connection with a slide fastener or zipper coin purse of the type illustrated in Figure 1, the details or parts of which will be described in connection with the operation of the attaching device. It is: to be understood, however, that other slide fastener types of closed articles may be assembled by the device, the'sections of which, of course, are of a size and design to correspond with the article which is to be made. Y

In the present showing the article is a coin purse of the slide fastener type, the principal parts of the purse consisting of a back member I, constructed of leather or other suitable material, comprising two back sections integrally connected by an intermediate hinge portion notched at opposite ends similar to the lining member illustrated in Figure 9. The inner surface of the coin purse backmemb'er I has the margins thereof covered. with adhesive 2 which also covers the inner surface of the hinge portion of the cover member as illustrated in Figure 3. The closure unit for the coin purse comprises a cloth or tape portion 3, the metal talons 4, a metalslide 5 coacting with the talons 4 and an actuating ring and chain 6 for actuating the slide 5 to close the slide fastener or open the same. The coin purse also includes a lining member I constructed of leather or any other suitable material shaped complementally to the shape of the purse back member I and having notches 6 in the sides thereof adapted to be positioned to register with similar notches in the back member I when the lining member I is superimposed upon the back member I as illustrated in Figure 10. One

side of the lining member I is completely cov-- scribedr Stitched or otherwise secured to one portion of the lining member I is a pocket III constructed of leather or other suitable material, the lower margin of which is extended and perforated to provide a hinge member I I to which a denominational coin holder I2 is secured. An arc-shaped end strip I3 is clamped to the tape 3 adjacent one end of thetalons -4 to form a stop for. the movement of the slide 5 at one end of the slide fastener. A similar stop member is provided at the opposite end of the slide fastener.

The attaching machine or device comprises abase section or. unit constructed of steel or other suitable metal and comprises a base plate I4. Projecting upwardly from two diagonally opposite corners of the base plate I4 are locking pins I5. Pivotally supported by means of screws I6 or the like to the two otherv diagonally opposite corners of the base plate I4 are the diagonally opposite ends of a pair of clamping bars or handles Il, each'of which is provided with an aperture I8 near the free end thereof for engagement over a pin I5 on the base plate I4.

Pivotally mounted on pins I6 projecting upwardly from diagonally opposite corner portions of the base plate I4 are the ends of the long arms of a pair of L-shaped clamps or half frame members 20. The long arm of each of the clamps 26 is provided with a notch 2| for receiving the ferruled or inclined end 22 of the shorter arm of the diagonally opposite clamps 20, as illustrated in Figure 3, when the clamps are in closed position. Integrally formed on the inner longitudinal edge of the long arm of each of the clamps 20 is a tapered finger or projection 23 which is shaped complementally to receiving notches 24 and 24 providedin opposite margins of a gauge plate or templet- 25 which is secured by means of screws or the like to the top central portion of the base plate I4. Each of notches 24-24 is provided with an outwardly inclined bottom as shown in Figure 7. The gauge plate.

or templet 25 is of less thickness than the thickness of the clamp 20 so that a pocket is formed, whenthe clamps are in closed position, for the reception of the back and lining members of the coin purse to be assembled. The gauge plate or templet 25 is shaped to conform to the shape of the. back and lining members of the purse, case or other article which is to be assembled. A keyhole opening 26 is formed in the top of the base plate I4 adjacent one side of the templet 25 with the narrow portion of the opening or slot 26 projecting toward the notch 24 on one side of the templet, as clearly illustrated in Figure 2. The opening 26 is provided for the reception of the chain and ring 6 during the assembling of a purse. The key hole slot 26 also has communicating with its restricted or narrow portion a slot 26a formed in the bottom of notch. 24 and "to receive lug 6a (Figure '7) formed integral with the slide and to which the chain 6 is attached.

The lug 6a is adapted to be slid lengthwise into the slide fastener unit in position. Projecting upwardly from the base plate I4 through the opening 24' adjacent one end of the boss 21 is a stud or pin 28. The pin or stud 28 isprovided as a stop around which the arc-shaped end clip I3 is adapted to be engaged to start the positioning of theslide fastener unit around the templet 25 to properly position the tape 3 to project upwardly as illustrated in Figures 6 and 7 above the clampingarms or frame members of the base unit.

In the operation of the device, the base unit is in open position; as illustrated in Figure 2, so that an adhesived coin purse back member I may be seated upon the templet with the adhesived portion facing upward, as illustrated in Figure 3.

I find that it is better practice to apply this member .I to the templet 25 after the slide fastener unit is disposed aboutthe templet, since the member I maybe readily inserted inside of the upstanding tape 3 and the tape may be thus used as a means for aligning member I with the templet 25. I

The slide fastener unit is first opened, and the end clip I3 (Figure 7) is engaged over the stud or pin 28, allowingthe talons adjacent the clip I3 to project down into spaced grooves 28a on opposite sides of the boss Z'Ijand formed in the inclined bottom of notch 24'. Then the parallel tape portions are spread apart in opposite directions and progressively worked about the margin of the templet 25 until chain slide 5i: opposite notch 24, at which time the chain 6 is dropped in slot 26.

Then chain slide 5 is inserted in notch 24 and its loop' 3a. is slid into slot 26a (Figures 2, 7, and 11) to center and hold the tape 3 in a fixed position relative to templet 25 and relative to member I which is thereafter placed on the templet as previously noted.

Before folding over the tape 3 onto the adhesived sections of the purse back member'jl the clamping arms or frame members 20 are swung from the open positions illustrated in Figure 2 into the closed positions illustrated in Figure 3 allowing the talons 4 to seat in grooves 29 provided in the clamp members 20 as illustrated in Figure 6 to firmly clamp the slide fastener unit around the templet 25. After the clamps 20 are moved into closed position the locking bars or arms I! are swung inwardly from the positions illustrated in Figure 2 into the closed position as illustrated in Figure 3 and the bars are slightly lifted so that the apertures I8 engage over the v pins I5 on the base plate I4 to tightly lock the clamp members 20 to form a frarrie around the templet 25 holding the tape 3 in proper positions ready to have the same folded over onto the adhesived portion of the purse back member I.

The folding operation of the tape isadapted to be performed by a top section or upper unit of the attaching device. The tape folding and pressing unit or upper section of the device comprises a rectangular frame plate 30 constructed of steel or other suitable material and having four guide housings 3| secured diagonally upon the corners. Slidably mounted in each of the guide casings 3I is a handle or lever 32 which carries a pin or stud 33 Y which projects downwardly through a guide slot 34 in the frame 30 as illustrated in Figure 8. Rigidly secured to the lower end of each of the studs or pins 33 is a tape folding and presser shuttle or slide shutter 35. The slidable shuttles 35 contact the bottom surface of the frame 30 and slide-in guide recesses or passages formed between the series of guide plates 36 and 31 secured in spaced relation on the bottom of the frame 30 and affording diagonal guide recesses whereby the shuttles may be moved inwardly by means of the handles 32 from the full line positions of Figure 5 into the dotted line positions into contact with the braidor tape 3 to uniformly fold the same inwardly from the position hesived part 2 of the coin purse back I and press said tape against the inner marginal face of the coin purse back member I as shown in Figure 8 with the excess material of the tape at the corners of the purse being uniformly folded and'pleated as shown in Figure 10. I

Two of the shuttles 35, positioned diagonally opposite one another, are provided with guide slots 38 which register at one end with openings 39 (Figure 4) provided in the frame 30 and continuing upwardly through two diagonally opposite sides of a pair of the guide housings 3! for the reception of the upper projecting ends of the pins I9 on the base plate I4 for the purpose of properly centering the frame plate 30 of the top section of the device over the base sections after an adhesived coin purse back member I and a slide fastener unit have been clamped in position as illustrated-in Figure 3.

Slidably mounted on opposite sides of the'top of the frame 30 are two oppositely positioned handles or levers 40 provided with slots 4i through which guide screws 42 project withthe inner ends thereof being secured in the frame 30. Pivotally mounted on the under side of each of the handles 40 at the outer ends thereof. are the outer ends of a pair of folding and pressing shuttles 43, the inner ends of which are shapedto provide fingers 44. shaped to engage the end porillustrated in Figure 7 over and against the adone another the pivoted shuttles 43 move inwardly from the full line positions of Figure 5 into the dotted line positions and gradually separate so that the end portions of the tape are folded transversely across the coin purse back- I against the adhesived middle portion thereof to complete the folding and the pressing of the tape against the inner surface of the coin purse back member I so that the assembled coin purse back member and the slide fastener unit are ready to have the coin purse lining member I secured in place.

After the tape has been uniformly folded over and pressed in position against adhesived portions of the coin purse back member I, the upper section of the device is lifted off of the base sectic-n. The lining member 1 of the coin purse is now adapted to be placed in position with the adhesived side 9 thereof positioned downwardly so that the lining member may be placed in position as illustrated in Figure 10 and pressed downwardly by hand to enclose the folded portion of the tape 3 between the coin purse-back l andthe lining member 1.

The partly assembled coin purse is now removed from the base unit'and the margins of the lining together with the side margins of the pocket ID are run through a stitching machine to stitch'the back member I, the lining I and the pocketllltogether. After thestitching operation the denominational coin holder I2 is secured to the hinge member ll of the pocket ill by means of rivets or the like thereby completing the assemblage of the coin purse which may be conven iently closed oropened by sliding the slide 5 by means of the pull chain and ring 6.
